This can be caused again by incorrect details used in your SMTP plugin (double check not only the username and password but also the port and encryption used).
By using logging, you can easily identify when errors occur, and why they are occurring.
Reviewing your logs will allow you to see where the notification might be failing, and correct the issue if it’s within the scope of Gravity Forms side of things.
Sometimes, due to server settings or e-mail reliability issues, using PHP sendmail does not work.
